T0 aZZ whom, it flung con/007%.-

Be it known that I, Tnorms PATES, a citizen of the United States,residing at Alton, in the county of Madison and State of Illinois, haveinvented a new and useful Improvement in Three-Horse Draft-Equalizers,of which the following is a specification.

My invention relates to a three-horse draftequalizer for use on plowsand other machines in which it is desirable that the hitch shall beshort, with the horses close back to the plow.

My invention will first be described in the specification with referenceto the drawings, and afterward pointed out in the claims.

Referring to the drawings, like letters refer to like parts in all thefigures, in which Figure 1 is a perspective view showing the front sideand top of a set of three-horse draft-equalizers. Fig. 2 is aperspective view, the same as Fig. 1, with the several partsdisconnected and apart, showing the construction of the said parts. Fig.3 is a plan or top view showing how the hitch is made short, in that thetracehooks 7b and h are all but a short distance in advance of theclevis c, which connects the plow. Fig. i is a rear view showing how thesingle-trees b are over the double-tree a, and the triple-tree (Z underthe said double-tree. Fig. 5 is aplan or top view showing the movementof the parts, and how, when one singletree falls behind the other, thetrace -hooks h on the triple-trees keep parallel to each other.

All the figures represent and show my improvement in a set ofthree-horse draft-equalizer, in which a represents a central doubletreeor evener, on both ends of which is connected a triple-tree, cl, whichhas its long arm extending inwardly and provided with a tracehook, h,and its short arm extending outward, to which is connected asingle-tree, b, and it will be observed that both ends of the said setare alike in construction, both ends of the said double-tree carrying atriple-tree, and both triple-trees carrying a single-tree. The saiddouble-tree may be of ordinary construction, as shown, made somewhatlonger than the on dinary two-horse evener. The said singletrees may beof ordinary construction, with trace-hooks h, as shown, and the saidtripletrees may be the ordinary triple-tree,in which one arm is doublethe length of the other arm, as shown, in which I provide the said longarm with a trace-hook, h, as shown. In my improvements the saidtriple-trees are placed n11- der the double-tree, a, and the saidsingle-trees are placed over the triple-trees above them sufficient toclear the double-tree. Two blockwashersflc 7a, are placed between thesaid sin gletree and triple-tree, and a plate or washenf, may beinterposed between the said double-tree and triple-tree to clear themfrom chafing, as shown. The said block-washers 70 may preferably beprovided with the pins 12 n, which enter holes in the woods, therebykeeping the said washers from turning on the woods, that the turningshall be on the meeting faces of the said washers, as will be understoodby inspecting the drawings. The bolt j is placed vertically through thesingle-tree b, the two block-washers 7c is, and the short arm of thetriple-tree d, as shown, and the well-known hasp on maybe used with thesaid bolt, as desired. The said bolt permits the single tree to swivelor turn thereon over the triple-tree, as will be understood by thedrawings. The bolt 6 is placed vertically through the double-tree a andthe triple'tree d, as shown, and the washer f may be interposed betweenthe said triple-tree and double-tree, as shown, and also the hasp 9 maybe used with the said bolt, as shown. The said bolt 6 permits the saidtriple-tree to swivel or turn thereon, as will be understood by thedrawings.

It will be observed that the distance between the two trace-hooks h h onthe tripletrees is about equal to the length of a singletree, and thatonly two single-trees are used in my improved set of three-horsedraft-equalizers, it being intended and provided that the traces of thecenter horse of the three shall be hitched direct to the hooks h on thetriple trees, obviating the use of a single-tree for the center horse,as will be understood by the drawings.

It will be observed that by reason of the triple-tree being under thedouble-tree and the single-tree over the triple-tree, the trace hooks hand h are all about on a line a short distance forward of the clevis 0,to which clevis a plow may be connected, whereby the horses may all behitched close back to the plow, as desired.

It is obvious that my improved set of threehorse draft-equalizers may beused either side up-that is, they may be inverted and the top sideturned down.

I am aware that it is common to connect a triple-tree to both ends of adouble-tree, both said triple-trees carrying a single-tree. Therefore Ido not broadly claim such; but I am not aware that anyoneh as heretoforeconstructed a three-horse draft-equalizer in the peculiar manner hereinshown and claimed.

Having thus set forth my invention, what I claim, and desire to secureby Letters Patent,

The combination of the central double-tree, two triple-trees, bolt 6,and hasp g, one of the said triple-trees pivoted to each end of the saiddouble-tree by means of the said bolt and hasp, as shown, the twosingle-trees, blockwashers 76, provided with pins a, bolts j, andv haspon, one of the said single-trees pivoted to the short arm of eachtriple-tree by means of the said bolt j, hasp m, andtwo of saidblockwashers, as shown, and for the purpose specified.
